IMPROVEMENT IN CHlMNEV-COWLS.

Specification forming part of Letters Patent No. 166,968, dated August24, 1875; application filed July 10, 1875.

To all whom it may concern:

Be it known that I, EMANUEL (low, of the city, county, and State of NewYork, have invented a new and Improved Chimney-Cowl, of which thefollowing is a specification:

In the accompanying drawing, Figures 1 and 2 represent, respectively,vertical central and horizontal sections on the lines o 0 and w a: of myimproved chimney-cowl and Figs. 3 and 4 are vertical central andhorizontal sections of a modified form of the same.

Similar letters of reference indicate corresponding parts.

My invention relates to an improved chimney-cowl that secures aneffective draft in the chimney in whatever direction the wind isblowing, the wind assisting the draft, and rendering thereby the workingof the chimney reliable in any weather, so as to prevent smoking andother inconveniences.

The invention will first be fully described, and then pointed out in theclaims.

In the drawing, A represents a chimneycowl, which is made of suitablesheet metal, of round or polygonal shape, and secured, by a chimneyconnectingtube, B, and cap-piece G, rigidly to the crown or top of thechimney. A series of vertical partitions, D, run at equal distance fromeach other in diametrical direc tion from the end of the chimney-tube,and form, with the straight or conical top and bottom plates E E, anumber of channels, that taper toward the communicating apertures 0.,arranged around the end of the chimney-tube.

The wind passes readily along any one or inore of the radiating channelsfrom whatever direction the same may come, and then across thechimney-tube to the diametricallyopposite channel, which assists, by itswidening shape, the passage of the wind, and creates also, by the crossdraft, a supplementary draft in the chimney, and thereby the escape ofthe smoke with the wind. This is efl'ected in every direction withoutany chance of damage or disarrangement to the operating parts, the cowlbeing perfectly reliable in its work.

For the purpose of excluding the rain from the chimney theexit-apertures of the cowl are arranged at some distance above the endof the same, and an additional base-chamber, F, formed around the same.

A central diaphragm, G, is attached, in suitable manner, above thechimney-tube, to conduct any entering rain sidewise to be collected atthe bottom of chamber F, and discharge through an exit-spout, b, to theoutside. This water-collecting chamber may be arranged with little extraexpense in connection with the inclined bottom plate of the cowl, whileit imparts, at the same time, a more ornamental appearance to the same.

Having thus described my invention, I claim as new and desire to secureby Letters Patent- 1. The combination of cowl A, tube B, cap 0,partitions D, and plates E with base-chamber F, in the manner and forthe purpose described.

2. The combination of chamber F and diaphragm G, to conduct therain-water to spout b, in the manner specified.

EMANUEL COLE.
